To all whom t may concern." Y Y Be it known thatI, Romina1 BoYLL, :i citizen of the United States, residing at Terre Haute, county of Vigo,-State of ndiana7 have invented certain new and useful Improvements in Electric Tax Sealers; and l dohereby declare the following to be a full, clear, and exact description of the invention, such ask will enable others skilled inthe art to which it appertains to make and usetlie saine.

The present invention relates to improvements in electric wax sealers. andmoreparticularly refers to an improved instrument for the making of wax sealsoiijletters, packages, etc.

An object of vthe invention is to provide an improved wav sealer in Vwhich the combined operations of melting, depositing and stamping the wax will all be'peritormed through a single agency which is driven through two complete strokes including the entirecycle oi. operation.

Another object of the invention resides inV providing an improved .wax sealer of a simple and inexpensive construction with a minimum of parts grouped compactly together andu forming an attractive instru-ment.

A still furtherobject off 'the invention is to provide a machine in which a minimum ainouiitoiE the electric current will be consiimed in the operation of heating the wax l and in which the operation of the machine will be simple and uniformly effective. Y

With the foregoing and other objects in view, the invention will be more fully de-v scribed hereinafter, and will be more particularly pointed out in the claims appended hereto.

Referring more particularly to the drawings, l designates a casingr having asuitable base 2 by which it restsfupon a suitable support, and 3 represents an extension tube erected onthe top Vof the casing 1. ,An opening 5 in the top 4 ofthegcasing serves to set up a communication between the interiors or the casings and eXtension'tube 3. A tube or holder 6 for a stick of wax is fitted to reciprocate vertically in the extension 8 and is providedy with a flange 7 at an appropriate point for-,cooperating with the internal shoulder 8 made at the top of the extension 3V whereby to limitthe upward movement or the tube or holder 6 in which it is iniuenced by a coil spring 9 having its upper end engaging beneath the Harige 7 and yits lower end *taking .against an internal Hangs 10 projecting Jfrom and into the lower portion of the extension 3. c

A top l1 is' hinged to the` tube or holder 6 as represented at 12 Yand serves to give acexplained.

Arms 13 in appropriate numbers'are riveted or otherwise secured to the lower end of the tube or holder 6 and project beyondthe lower end thereof. These armsl inthe instance shown in the lliwiigsV aref fourin'- number and are situated at 90o apart so that they fulfill the function of grasping and retaining the wax sticlr in place, while at the same timepermitting of theactive circulation of air about the same and about the lower parts carried thereby. A iing 14 passes about within thestrips 13 at their medial portions in order to reinforce the same and to prevent their spreading. The arms at their lower ends carry a head 15, shown more particul-arly in Figs. 7 j and 8, and which is either of rectangular or cylindrical construction as may be required to receive the various cross sections of the wax stick. The head 15 has pivoted therein a pair of jaws 16 and 17, the pivot points being indicated lat 18 and 19 and being situated at the upper divergent ends of the jaws. The jaws are each substantially triangular in side elevation or appear scoopshaped, they being normally held together along their meeting edges in order to form a closed trough in which the wax at the lower end ot the stick may be melted as presently referred to. I j

` Lugs"20 on the jaws 16 and 17 are provided to receive the ends of'coil springs 21 serving to yieldablyv hold the jaws together in the manner indicated in Fig.- 9, but lpermitting of their opening, as illustrated in Fig. 10.

The jaws 16 and 17 are provided withperforated lugs 22 and 23 to receive electric heating elements 24 and 25 in which are included suitable resistance coils of a character that are well-known and form no part of the present invention, sothat they are not particularly illustrated. 1 i

The electric heaters 24 and 25 normally occupy the position shown in Fig. 1 in which they swing down by gravity away from the inclined faces of the jaws 16 and 17.` Webs 26 and 27 project at right angles outwardly from the electric heating elements 24 and 25 and receive the ends of chains or other Suitable, flexible connections 23 and 29. Perforated ears 30 and 31 extend from the interior walls of the casing lat a `suitable elevation and receive theopposite ends of the chains 28 and 29.' Theseehains are of appropriatelengths to subserve certain funcl l tions hereinafter pointed out.

Contact fingers 32 and 33 .project outwardly from the free end of the electric heating elements 25, as shown in Figs. 1 and 2. These two contact fingers are connected toA opposite ends of thel resistance coil. The

element.

finger 32, for instance, carries current from an exterior source into the coil, while the finger 33 serves to carry olf the current after it has traversed the windings of the heating `Cooperating contact lingers 34 and 35 projectdownwardly from the head 15 so as to be engaged respectively by the fingers 32 and 33 when the heating element 25 is caused to swing up against the inclined `faces of the jaws 16 and 17 in'which position it is illustrated in Fig. 3. The fingers are preterably of spring material in order that they may come into a yielding engagement and form an effective contact. The opposite heating element 24 is provided with similar contact fingers 36 which co-act with further contact fingers 37 depending from the head 15.

IThe current is received from the source through a lead 38 which is connected to a binding post 39 near the lower end and at one side of the extension 3. A contact plate 40 isin connection with the binding postglt) and is insulated from the wall of the enten# sion. Such contact plate 40 projects in the iied by the wax holder or one of its arms 13, the meeting edges of theplates 40 Aand 41 being beveled in order to facilitate their engagement when the holder is depressed to l.. the position shown in Fig. 3. The contact plate 41 is likewise insulated asindicated romthe surrounding members ofthe wax holder and it has vconnection vwith a conducpath of a companion Contact plate41 carl tor 42 which extends down within the arm 13 with which the plate 41 is associated. A

The eonducto-r`42 is an extension through the arm 13 of the contact finger 34 as will be vseen in Fig. 2. The 'opposite contact finger' 35, also seen in Fig. 2is a'prolongawhich supplies current to the resistance coil' in the electric heating'element 24. The current, after passingy through the coils of the heating element 24, will. pass through the fingers 36 and 37 and toa contact plate 44 similar to the plate l41'.` The plate 44 j,

cooperates with a companion plate-45 associated with a binding post 46 with 'which the opposite wirei47 ot the source of: current is `connected.4 Of course, otheicircuit closing inea-ns may be used.

An impression producing die is cariied on the lower ends of alims 49 pivoted as at 50 to the extension 51 of the. arms 13, as seen in Figs. Gand S. The arms 13 are offset at `connection with the head 15. arms 49 are provided with `a rightangular piece 52 carrying a pin 53y for engagement in the notch 54 produced in the lower end of the lever 55. This lever is fulcruined as indicated at 56 in the upper portion of the casing 1- near the wax holder and is adapted to be engaged by the beveled lower edge of The Kv a toe 57 formed on a handle 5S which is pivi oted at 59 within the casing 1 and operates in a. slot 60 made in its top.

Beneaththe die 48 are a-pair of swinging plates 61 and 62 pivoted at 63 and 64 within 4the casing 1 and adapted to hold oiled pads 65 and GG in such a waythat they are presented to the lower face of the die 43. Jointed arms G7 and 68 are coupled between the plat-es`61and 6,2 and the pivot pins 50 of the arms 49 for the purpose of raising the plates to the horizont-al position Yafter they have bcendepressed, as shown in Fig. 4.

A coil spring 69 is coupled between the lever 55 and the casing 1Y in'or'der to draw the lever norm ally downward to the position indicated in Fig 3 when it is unrestrained by the toe 57. Aspring latch '70 is carriedk by the support of the extension 3 and projects through an opening 71 made there in to permit the latch :to projectinto the path of the iiange 7 on the tube 6. This is shown in. Fig. 4. j i Y The operation of the invention is substantially as follows.A The parts arevnormally in the condition shown in Figs. 1 and` 2. The lid 1'1` is lifted, and.` afbarI of wax or analogous material inserted into lthe holder 6 and pushed down therein until the lower end of the wax lbar enters the trough formed by the pair of coacting jaws 16y and 17. The'lowei portion of the bar will be4 confined by the arms 13 and ring 14 while exposing the majority of itsV surface tothe air circulating through the interior of the apparatus. f l l lVhenit is -desired to seal an envelope, package, or the like the entire instrument is ,placed with its ibase 2 over thepackage so that the upper portion of the package to besealed is exposed to the action of the interior parts. The tube G is then depressed, by engagement of the hand with the upper surface of thecover 11, 'to the position shown in F igs. 3and 4, the latch 70 being projected into the casing so as to engage with `the flange 7 and hold the parts 'in this condition for a. suitable intervalof time. vThis interval of time is that necessary to the heating and melting ofthe desired quantity of wax.` y y I The downward movementiof the holderto this positioncauses the chains or connections 28` and 29 to be brought to a taut condition such kas will swing the electric heatingelements24 and V25 Yabout their pivot points 22 and up againstthe inclined faces of the jaws 16 and 17. The contact fingers will be thus closed and the circuit'completed through the coils which will thus transmit heat through the comparatively thin metallic walls of the jaws to the lower end of the wax bar within the trough. i

kA few seconds only will be required to melt a suitable quantity. of lthe wax which will flow down intol the closed apex of the delivery jaws and will be held there until the jaws are opened. VThis opening of the jaws is'L accomplished by la `further downward movement of the holder 6. .f This movement impressioncontainedon the kdiek face.

accomplishes the opening of the jaws, for instance to the position shown in Fig. 10 by reason of the pull exerted on the pivot points lowerV ends of the jaws on to the package placed beneath the machine. i j

During all' of thesemovements the impressiondie 48 will be ,swung out to the position indicated in Figs. 3 and 4 so as n ot to interfere with the'depositingof the melted wax on the package.v -`This swinging of the die vis accomplished through kthe medium 'of the lever55 which clings in the pin 53 of the projectingpiece 52 and therefore causes the swinging of the die aboutI its pivots 50. The dieextends outwardly through an opening k7 2 made near one side of the casing wall for this purpose. i

i After the wax is delivered to thek package, the holder itself is allowed to ascend, the latch v meantiinespringing out of the opening 71 so 'as not to kinterfere with the operation of the spring 9 .in raising the wax holder. lhen in the lraised position the handle 58 is swung over to the. position shown in Fig. 5 against the'extension 3 causing the'toe 57 tol engage the adjacent portion 'of thel lever 55 and raisethis `lever whereby'to free the V I notch4 V54vfrom the-pin 53. l

n The next operation is to depress the tube 6 a second time. :During thissecondmovement the die will remain in advance of the delivery-jaws and *willy descend onA to` the melted wax lately ldepositedV on the package.V The wax WilL'tlierefore, acquire the After the impression is made the holder is'ready to' ascenda second time, thel pin reengaging in the notch 54 of the lever 55, and by swinging the handle 58 tothe initialoutward position, the'apparatus is putin condition to be subsequently operated.
